GUIDE MEANS FOR wnnrnas AND SIMILAR MAUI-HATES.

T 0 all whom it may concern.

Be it known that I, ALONZO E. RHoanns, a citizen of the United States, and resident of Hopedale, county of Worcester, and State of Massachusetts, have invented an Improvement in Guide Means for Warpers and Similar Machines, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to yarn winding machines wherein the yarn is wound upon a core in a cylindrical mass by means of 'a driven winding drum mounted in parallelism with the core and acting by peripheral engagement with the yarn mass on the core to efl'ect the winding operation.

The invention in itspreferred .form is particularly designed for a warper wherein the yarn is wound upon a warp beam comprising a core, heads in the form of disks at each end and journals, but it is equally applicable in its broader aspects to any form of yarn winding machine of this type wherein it is desired or necessary to maintain the longitudinal position of the yarn receiver in a relatively fixed position with respect to the frame and the winding drum.

The object of the invention is primarily to provide means in combination with the elements of the machine involved which act to prevent longitudinal movement of the yarn receiver relatively to the drum during the winding operation or which act to maintain the yarn receiver during the winding operation in fixed longitudinal position.

In this type of machine there is necessarily a relative bodily transverse movement between the core, on which the yarn is wound and the winding drum in order to effect the winding operation and in. the warper one of these elements, usually the beam. is journalled in arms hinged or movably secured to the frame so as to allow the beam to swing or move bodily transversely toward and from the drum. The winding drum usually comprises a relatively thin cylindrical iron shell open at the ends and if the longitudinal position of the beam is not maintained fixed the longitudinal move ment of the beam due to the longitudinal shifting of its bearings or the yield of the supporting arms allows the ends of the shell of the winding drum to engage and grind against the heads of the warp beam often injuring or damagingthe winding drum. Furthermore, this grinding action often so reducesthe length of the winding drum as to prevent the proper pressure being applied tothe ends oi'tlie cylindrical yarn mass wound on the beam. This is highly undesirable as it results in soft yarn at the ends of the'mass and unequal tension throughout the yarn mass.

l/Vith this invention the warp beam or other yarn receiver is accurately maintained in a fixed longitudinal position so that during the winding operation and during the transverse movement of the drum or yarn receiver there is no danger of the heads of the warp beam engaging the winding drum. Consequently the winding drum is uninjured and its length maintained. The pressure on the yarn mass is kept uniform throughout and accuracy in the placing of the yarn upon the drum or yarn receiver is insured.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

In the drawings:

The invention in a preferred form is herein shown embodied in an ordinary and familiar type of warper and, as the invention is only concerned with "a, specific feature of the operation of the warper, it is only necessary to illustrate and describe, those features of the warper directly concerned with the invention. i

This type of warper comprises a frame including vertical side members 1 and 2 which support the various shafts and other parts of the war-per. The yarn receiver,

which in this case is a warp beam, comprises a cylindrical core 3 on which the yarn mass is wound, journals 4: projecting at each end of the core, and generally flat or diskshaped heads 5. These heads on the interior oppositely facing surfaces are flat and on the exterior surfaces are generally ribbed and braced as illustrated. The journals of the warp beam are usually mounted in bearings 6 formed in the ends of arms 7 movably mounted on the frame. These arms allow the warp beam to. move transversely or swing toward and from the frame. The warper beam is a very heavy structure as the heads are made of cast iron or steel and the heavy mass of yarn wound thereon greatly increases the total weight supported in the journal bearings.

The winding drum usually comprises an iron cylinder 8 having a central shaft presenting the journals 9 mounted in bearlngs 10' on the frame. The drum shaft extends parallel to the beam shaft and the drum is rotated in the usual manner. The periphery of the drum rests against the yarn mass on the core of the beam and thus acts to effect the winding operation, the beam swinging or moving transversely away from the drum as the operation proceeds. While the relative transverse movement which takes place between the winding drum and the yarn receiver is, in the illustrated case, secured by the transverse bodily movement of the yarn receiver, it will be understood that the present invention in its broader aspects is independent of the manner in which this transverse relative movement is secured. Furthermore, while the yarn receiver is illustrated as a warp beam having heads, the particular form of the yarn receiver is not important in the broader aspects of the invention.

In the preferred construction illustrated the fixed longitudinal position of the yarn receiver 1s secured and thus longitudinal movement'wlth respect to the frame and the winding drum is prevented by means of anti-friction rollers mounted at opposite sides of the frame and having positioning engagement with the yarn receiver, and in this case with the heads thereof, during the winding operation or during the relative transverse movement of the yarn receiver and drum. For this purpose brackets 11 are mounted at each side of the frame. As illustrated, each bracket comprises a foot 12 provided with a'longitudinal slot 13'by means of which the bracket is supported on the cap 14 of the journal bearings 10 and held in longitudinal adjustment by the usual bolt 15 which secures the cap to the base of the journal bearings 10. Each bracket rises vertically and then extends outwardly plate 16 is secured a stud 17 projecting upwardly at right angles to the plate 16 or at an acute angle to the vertical. An annular shell 18 projects upwardly from the plate 16 concentrically with the stud 17. The guiding or anti-friction roller 19 is journalled on the stud 17 and has a shank 20 extending into the chamber formed between the stud 17 and the shell 18. The roller is held in place by any suitable means such as a cotter pin 21 passing through the upper end of the stud.

The upper end of the roller 19 presents an annular chamber 22 having a conical bottom surface 23 extending upwardly toward the stud and, preferably at its center, extending downwardly toward the stud to form the small concentric recess 24. An

annular inwardly projecting flange 25 par tially incloses the chamber 22 at the top. This construction of the upper end of the roller is provided to prevent oil used in lubricating the roller on the stud 17 from being thrown out or passing from the bearing onto the yarn receiver or warp beam or onto the yarn wound thereon. Great damage might be done to the yarn if the oil got onto the yarn or got onto the beam and therefrom onto the yarn. In the present construction any oil is either caught between the shell 18 and shank 20 or is caught in the chamber. 22 and guided back onto the stud. The small concentric recess 24 enables the oil readily to be applied to the stud and also assists in directing the oil caught in the chamber 22 back onto the stud.-

The winding drum 8 is preferably constructed in the usual manner so that the outer iron shell presents between itself and the journals 9 at each end a recess in the end of the drum. By mounting the brackets 14 on the bearing caps the substantial portion of the brackets and of the anti-friction I rollers are mounted in the recess of the drum so that the peripheries of the rollers only project slightly beyond the ends of the drum as shown in Fig. 2.

The operation of the device is apparent. The brackets 14 are adjusted longitudinally so as to allow the peripheries of the antifriction rollers 19 to project equally and slightly beyond the ends of the winding drum and in positioning engagement with the inner surface of the beam heads. They should not be so adjusted as to bind upon the heads, and slight play may be allowed so long as the positioning engagement is such as to prevent the beam heads from contacting with the drum during the Winding operation. As the drum is rotated, the

heads engage and rotate the anti-friction rollers 19 without impedingthe rotation of the drum, and as the beam slowly swings or mores away from the drum its longitudinal position is maintained with ami11imum amount of friction.

It will thus be seen that the invention obviates the difiiculties heretofore encountered and insures the accurate longitudinal position of the beam or yarn receiver with respect to'the winding drum and the frame at all times.
